We describe and evaluate the first year efforts of the Colorado Physics Teacher Education Coalition (Colorado PhysTEC), which is designed to increase the number and quality of preparation of future pre-college physics teachers. The Colorado PhysTEC program partners the Department of Physics, the School of Education, and other University of Colorado programs (particularly STEM-Colorado), with local schools and K-12 physics teachers. We report on efforts to engage students in transformed teaching practices, programs to create educational partnerships among all of the participants, and research that documents local educational practices and larger features of sustainable and scalable educational transformations.
